Title: Suspension system for motor vehicle with actuator(s) between bodywork and wheel axle bearer - has valve arrangement and servo valve increasing springed rigidity if effectiveness of pressure control arrangement is insufficient
Inventor: SCHEFFEL MARTIN
IPC: B60G17/04
Filed: 1992-06-26
Abstract: The actuator provides at least one working chamber contg. a compressed medium for variable working pressure.

Title: Bicycle shock absorber
Inventor: SOIU PETER
IPC: B62K25/16
Filed: 1993-04-28
Abstract: The shock absorber has a wide variety of uses in mechanical engineering. In contrast to other means of locomotion, the shock absorber has not yet been used in the construction of bicycles. The novel bicycle shock absorber has been developed in order to absorb the shocks which act on the bicycle and hence on the cyclist. Transmission of the impact effect to the shock-absorber parts in the upper region causes the effect to be passed on to the spring which ensures optimum absorption of the shocks.

Title: Needle bearing
Inventor: GIESE PETER DIPL ING DR
IPC: F16C19/46
Filed: 1993-09-22
Abstract: On its races (6, 8), a needle bearing has radial flanges (11, 12), between which an axial slip ring (13) is arranged. Oil under pressure flows out of the interior of the bearing, past a piston ring (14), into a pressure chamber (15) delimited by the flanges (11, 12), the curved surface of race (6) and the axial slip ring (13). From there, the oil under pressure flows between the front face of flange (12) and the axial slip ring (13) to the outside of the needle bearing. The axial force acting by virtue of the pressure prevailing in the pressure chamber (15) brings about a reduction in the friction between the axial slip ring (13) and the flanges (11, 12). <IMAGE>
